Allow non-overflow ops in reductions
2015-08-01 Tom de Vries <tom@codesourcery.com>
* tree.c (operation_can_overflow, operation_no_trapping_overflow): New
function.
* tree.h (operation_can_overflow, operation_no_trapping_overflow):
Declare.
* tree-vect-loop.c (vect_is_simple_reduction_1): Use
operation_no_trapping_overflow. Allow non-overflow operations.
* graphite-sese-to-poly.c (is_reduction_operation_p): Allow non-overflow
operations.
* gcc.dg/autopar/reduc-2char.c (init_arrays): Mark with attribute
optimize ("-ftree-parallelize-loops=0").
Add successful scans for 2 detected reductions. Add xfail scans for 3
detected reductions.
* gcc.dg/autopar/reduc-2short.c: Same.
* gcc.dg/autopar/reduc-8.c (init_arrays): Mark with attribute
optimize ("-ftree-parallelize-loops=0"). Add successful scans for 2
detected reductions.
* gcc.dg/vect/trapv-vect-reduc-4.c: Update scan to match vectorized min
and max reductions.
